I can't log in and register pdp toolbox

Question

I successfully registered using the WeChat QR code, and then it showed: Username (ID number).

So when I went back to the computer, PHP still asked me to log in again, and I couldn't log in,

I can’t log in using my WeChat account, what should I do?

I want to register again, goto I successfully registered using the WeChat QR code..

I can’t log in and register.
